The present invention relates to new and useful improvements in buildershardware, and more particularly it pertains to a new and improved formof window lock.

It is one of the objects of the present invention to provide a new andimproved window loclr which will securely hold two sliding sash membersagainst movement relative to each other.

A further object of the invention resides in the provision of a deviceof the aforementioned character which will automatically move to openposition from locked position when properly operated.

It is a further object of the invention to provide a window lock whichwill prevent operation to released position bythe insertion of a toolbetween the meeting rails of a window sash.

With the above and other objects in view which will become apparent asthe nature of the invention is better understood, reference will be hadto the accompanying drawings, wherein:

Figure 1 is a transverse sectional view taken through the meeting railsof two window sash and showing a lock constructed in accordance with thepresent invention in its closed position,

Figure 2 is a horizontal sectional view showing vthe lock in section,and the meeting rails in top plan, and;

Figure 3 is a detail perspective view of the loch, the loclrbeing shownin its re` leased or open position.

Referring' more particularly to the drawings, the reference characters 5and 6 designate the meeting rails of an inner and `outer window sashrespectively.

A lock constructed in accordance with the present invention, preferablyincludes two housing members 7 and 8 which may be formed of any suitablematerial such as sheet metal and which are secured to the meeting railsof the outer and inner sash 6 and 5 respectively. The housings 7 and 8are secured to their respective sash by means of screws or he like 9which preferably pass through the housings near 'the ends thereof.

Pivotally connected as at 10 to the housing 1931. Serial No. 542,404.

7,'there is a swinging member 11 whichmember has a right angularextension 12 provided with a pair-.of'spaced openings 13 "as best'illustrated in Figure 3. 'The pivotal pointv Y of the member 10 consistsof'a rodla mounted 55rk in an opening 15 inthe top wall of the housing 7andsu'rrounding the rod, and having one end 16 engaging the memberlO'and the other end 17 engaging the housing, there, is a coil springV18 which tends to holdv theV 6o swinging memberl() in its yuprightoropen position. j Y f The housing 8 is provided in its u'pperwall witha slot or the lilre 2O which is adapted to receive 'the right angularextension12 of 65 the member l1() when the-latter is moved to itslocking or closing position. As best illustratedfin Figure 2, there aretwo guide rods 22 which extend transversely of the housing Vmember 8 andslidably mounted on these guide 70 rods, there is a cross bar 23 thelatter being provided with openings to receive the guide rods 22. Thiscross bar 23 carries a plurality of projecting lugs or the like 24 whichare adapted to pass through the openings 13 here- 75 toforementionedwhen the swinging member l0 is moved to its locking position and thesemembers alsopass in the openings 25 in the front wall of the housing 8.A bowed spring 29 is'employed for maintaining the 8o cross bar 23 in itsforward or locking position, and an operating member in the form of ashaft 30 having an operating knob 31 is attached to the cross bar 23 andprojects through an opening in the front wall of the $5-- housing 8 tothe exterior thereof.

From the foregoing it is apparent that with the parts in the position inwhich they are illustrated in Figure 3, it is only necessary to swingthe member 10 about its pivotal point 90 against the action of the hinge18 until the right angular extension 12 is positioned within the slot itbeing understood that the cross bar 23 will be depressed against thespring 29 to permit of this movement. After this has 9*? been done themember 23 is released `and the spring 29 forces the projecting lugs 24into the opening 13 to lock the member in its closed' position.

While the invention-has been herein illustrated in a preferred form, itis to be understood that the same is not to be limited to theconstruction herein shown, and that it may be practiced in other formsWithout departing from the spirit thereof. Y

Having thus described the invention, what is claimed as new and whatitis desired to secure by Letters-Patent ofthe United States, 1s:

A lock for windows comprising in combination with two window sash,` ahousing member carried by the meeting rail of each sash, a pivotedmember carried by one ofv l said housing members, a right angular extenfsion on said pivoted member, said right angular extension having a.plurality of open- V ings therein, a slot inone of the walls of theother housing,said slot adapted to receive the right angular extensionof the pivoted mem-A ber, andmeans for engagement with the openings inthe right angular extension, of the pivoted'member toflock it inthehousing, said last; mentioned means comprising a sliding bar, and a.`plurality ofA projections on said sliding bar for entrance into theopenings of thepivoted member and openings in the sidel wall of thehousing in which it is mounted, and a springfor moving said bar intolocking position.

In testimony whereof I aiX my signature.
